From b6392bd5b11d694a5d563d2ad1d88137d2cde036 Mon Sep 17 00:00:00 2001 From: Janusz Krzysztofik Date: Mon, 30 Apr 2012 19:26:09 +0200 Subject: ARM: OMAP1: Amstrad Delta: Fix wrong IRQ base in FIQ handler Commit 384ebe1c2849160d040df3e68634ec506f13d9ff, "gpio/omap: Add DT support to GPIO driver", introduced dynamic IRQ numbering of OMAP GPIO interrupts, breaking all IH_GPIO_BASE based IRQ number calculations. This issue was corrected in the OMAP GPIO driver and the related header file with commit 25db711df3258d125dc1209800317e5c0ef3c870, "gpio/omap: Fix IRQ handling for SPARSE_IRQ". However, the Amstrad Delta FIQ handler, which replaces the gpio-omap driver in serving GPIO interrupts on this board, still uses that outdated method. Fix it.

The commit above swapped the DSI1_PPID and DSI2_PPID register fields in CONTROL_DSIPHY to be in sync with the newer public OMAP TRMs(after version V). With this commit, contention errors were reported on DSI lanes some OMAP4 SDPs. After probing the DSI lanes on OMAP4 SDP, it was seen that setting bits in the DSI2_PPID field was pulling up voltage on DSI1 lanes, and DSI1_PPID field was pulling up voltage on DSI2 lanes. This proves that the current version of OMAP4 TRM is incorrect, swap the position of register fields according to the older TRM versions as they were correct.
